Front

What is the Third Angles Theorem?

Back

The Third Angles Theorem states that if two angles of one triangle are equal to two angles of another triangle, then the third angles are also equal.

Front

How do you classify triangles by their angles?

Back

Triangles can be classified as acute (all angles less than 90°), right (one angle equal to 90°), or obtuse (one angle greater than 90°).

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180°.

Front

If two triangles are congruent, what does that mean?

Back

Front

What is the formula to find the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

What is the relationship between the sides and angles in a triangle?

Back

In a triangle, the larger the angle, the longer the opposite side; conversely, the smaller the angle, the shorter the opposite side.
